Flat pricing, published

Pricing is now stated plainly and enforced as a product rule.

The plans in this release have since been replaced by one price per project; current pricing is the only price list.

• Flat plans. Verified restore, previews, custom domains, and export are included, never metered add-ons.
• A pricing calculator shows what your projects cost.
• Projects are confirmed to never pause: idle ones scale to zero and wake on the next request.
